drastic change in hairstyle that changes someone completely

Lately I have two programs that I seem to be committed to watch that is Canadian. I am not sure if you guys see them or not.
One of them is call City Line and the other one that started is called Bella.
Both of those shows show different helpful hints about how to make our wardrobe and hair etc more exciting.
Today I was watching Bella and this business woman had short hair but felt she needed an up to date hairstyle and wow did they ever do a great job on her. I had to look twice.
It started to make me think how much a hairstyle really can change our attitude or perpertive on life. IN college this classmate had this hairstyle that made her look so much older and she is only 24 and when she was going to a wedding in Montreal she decided to change it and wow did she ever look so chic. It just fascinate me how much something so small as a new style can make such a huge difference.
